Description

Technical Field

[0001] The present invention relates to the technical field of root water supply devices, and particularly to a root water supply device for seedlings in the central isolation belt of expressways. Background Art

[0002] For sound insulation, noise reduction, and environmental beautification, greening trees are usually planted in the central isolation belt of expressways. The trees can serve as a physical barrier, absorbing and dispersing part of the traffic noise, reducing the visual interference between oncoming traffic flows, and reducing the risk of accidents caused by driver distraction. Secondly, the trees can also beautify the environment of the expressway, enhance the road landscape, and make drivers and passengers feel more comfortable and pleasant during long-distance trips. Since it is not easy to irrigate the seedlings in the central isolation belt with a sprinkler truck, a root water supply device is usually used for water supply.

[0003] In the existing patent literature, a patent with a publication number of CN118318718B and a name of "A sunken potted seedling root water supply device and its water supply method". When this patent and many existing water supply devices supply water to the roots, they do not provide air or oxygen around the underground roots. When the roots absorb water, they will carry out respiration. If the roots are in a humid and oxygen-deficient condition for a long time, it is very easy to cause root rot, which is not conducive to the healthy growth of seedlings. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a root water supply device for seedlings in the central isolation belt of expressways. By setting a semi-encircling root air supply component, the outside air can directly reach the roots of the seedlings through the semi-encircling root air supply component, increasing the oxygen content around the roots, contributing to the respiration of the roots. Then, when water is supplied to the roots for a long time, the roots are not easily rotten, which is more conducive to the healthy growth of seedlings.

[0005] To solve the above technical problems, the technical solution of the present invention is realized as follows:

[0006] A root water supply device for seedlings in the central isolation belt of expressways includes two oppositely installed semi-encircling root water supply components, and the two semi-encircling root water supply components can form a complete encircling root water supply component;

[0007] A semi-encircling root air supply component is also inserted and installed in each semi-encircling root water supply component, and both the semi-encircling root water supply component and the semi-encircling root air supply component are buried underground;

[0008] A main water supply pipe is docked above each semi-encircling root water supply component, and the main water supply pipe is installed on the ground;

[0009] A water-jet drive mechanism is installed at the docking position between each main water supply pipe and the semi-encircling root water supply assembly, and an intermittent air acceleration flow mechanism is docked above each semi-encircling root air supply assembly. The water-jet drive mechanism and the intermittent air acceleration flow mechanism are at the same height and the water-jet drive mechanism acts on the intermittent air acceleration flow mechanism. When there is water flow impact in the water-jet drive mechanism, the intermittent air acceleration flow mechanism can be actuated through the water-jet drive mechanism to accelerate the air fluidity in the semi-encircling root air supply assembly.

[0010] With the above solution, first of all, by setting the semi-encircling root air supply assembly in this root water feeder, the outside air can directly reach the root system of the seedlings through the semi-encircling root air supply assembly, increasing the oxygen content around the root system and contributing to the root respiration. Then, when watering the roots for a long time, the roots are not easily rotted, which is more conducive to the healthy growth of the seedlings. Secondly, after the semi-encircling root water supply assembly of this root water feeder is inserted into the semi-encircling root water supply assembly, the whole semi-encircling root water supply assembly will be more stable, and it can restrain the root system of the seedlings to prevent it from extending outward and damaging the highway foundation. Finally, when this root water feeder is supplying water, there will be water flow impact in the water-jet drive mechanism. The intermittent air acceleration flow mechanism can be actuated through the water-jet drive mechanism to accelerate the air fluidity in the semi-encircling root air supply assembly, providing air with faster fluidity during water supply, further increasing the oxygen content around the root system and helping the roots to carry out respiration during water absorption.

[0011] As a preferred embodiment of a root water feeder for seedlings in the central isolation belt of a highway, the semi-encircling root air supply assembly includes a linear air pipe, and a plurality of horizontally arranged and vertically side-by-side distributed semi-encircling air pipes are connected to the linear air pipe. A plurality of air supply pipes distributed in a circumferential array are commonly docked on all the semi-encircling air pipes, and a plurality of air supply holes linearly arrayed along its length are opened on the air supply pipes.

[0012] With the above solution, in order to achieve uniform air supply, air is supplied from the linear air pipe into each semi-encircling air pipe, then enters the air supply pipe, and finally the air is discharged from the air supply holes to supply air evenly around the root system.

[0013] As a preferred embodiment of a root water feeder for seedlings in the central isolation belt of a highway, a plurality of slots distributed in a circumferential array are opened on the pipe wall of the semi-encircling air pipe, and each slot is filled with a water storage sponge section. Among them, the water storage sponge section is cut off one-third of its diameter along its radial direction, and a ventilation hole is radially penetrated through the center of the water storage sponge section.

[0014] With the above solution, in order to store the water around the root system, by setting up a water storage sponge section, the excess water in the soil will be absorbed and stored by the water storage sponge section, thus facilitating the subsequent supply to the root system; and one-third of the diameter of the water storage sponge section is cut off along its radial direction to prevent the water storage sponge section from affecting the normal transmission of air.

[0015] As a preferred embodiment of a water supply device for the roots of seedlings in the central isolation belt of an expressway, the water flushing transmission mechanism includes a water flow box body, and an impeller is rotatably connected inside the water flow box body; a guiding seat is fixed inside the water flow box body above the impeller; a transmission swing arm that can rotate with the impeller is fixedly installed outside the water flow box body, and the length of the transmission swing arm is greater than the length of the fan blade.

[0016] Among them, the guiding seat is inclined in a "slide shape", and an opening eccentric to one side of the impeller rotating shaft is opened at the bottom of the guiding seat, and the fan blade of the impeller corresponds to the lower part of the opening.

[0017] With the above solution, in order to realize the operation of the intermittent air acceleration mechanism, by setting up a water flushing transmission mechanism, when there is water flow impact in the water flushing transmission mechanism, the transmission swing arm rotates with the impeller, and the transmission swing arm will act on the intermittent air acceleration mechanism, thereby realizing the operation of the intermittent air acceleration mechanism.

[0018] As a preferred embodiment of a water supply device for the roots of seedlings in the central isolation belt of an expressway, the intermittent air acceleration mechanism includes an air box body, and a push block that can move up and down is installed inside the air box body. A corrugated air plug that is in interference fit with the inner wall of the air box body is installed outside the push block in a limiting manner; a main push rod vertically arranged is fixed above the push block; a guiding seat is fixed at the top of the main push rod, and the guiding seat is slidably installed on a guiding shaft one fixed inside the air box body. A spring one that pushes the guiding seat to move upward is sleeved on the guiding shaft one; a secondary push rod horizontally arranged and penetrating to the outside of the air box body is fixed on the side wall of the main push rod, and the secondary push rod is located in an avoidance groove vertically opened on the side wall of the air box body; the secondary push rod can be in contact with the rotating transmission swing arm, and when the secondary push rod is in contact with the transmission swing arm, it can press down the secondary push rod.

[0019] Among them, two symmetrically arranged one-way air inlet valve assemblies are also installed at the lower end of the air box body. The bottom of the push block is respectively connected to the one-way air inlet valve assemblies by two steel wires, and the opening and closing of the one-way air inlet valve assemblies are controlled by the steel wires; two groups of wire bundling rollers are fixed on the inner side wall of the air box body above the one-way air inlet valve assemblies, and the steel wires are simultaneously limited between the two groups of wire bundling rollers.

[0020] Among them, the one-way air inlet valve assembly includes an air inlet valve housing. An air inlet valve opening is provided at the center of the air inlet valve housing. A control valve core located at the air inlet valve opening is installed inside the air inlet valve housing. The control valve core can completely block the air inlet valve opening. The control valve core is slidably installed on a second guide shaft fixed inside the air inlet valve opening. A second spring for pushing the control valve core to move towards the air inlet valve opening is sleeved on the second guide shaft. A steel wire is traction-connected to the control valve core.

[0021] With the above solution, in order to accelerate the air flow in the semi-encircling root water supply component, when there is no water flow impact in the water flushing transmission mechanism, the transmission swing arm remains stationary and cannot press down the auxiliary push rod. At this time, under the elastic action of the first spring, the steel wire is taut, and the control valve core is pulled open by the steel wire to open the air inlet valve opening. At this time, the one-way air inlet valve assembly is in the open state, so that air can naturally circulate inside and outside the air box. When there is water flow impact in the water flushing transmission mechanism, the transmission swing arm rotates with the impeller. When the transmission swing arm rotates, it will press down the auxiliary push rod. At this time, the first spring is compressed and the steel wire is slack. The control valve core closes the air inlet valve opening under the elastic action of the second spring. At this time, the one-way air inlet valve assembly is in the closed state, and the air is compressed downward through the corrugated air plug, so that the air can circulate quickly inside and outside the air box.

[0022] As a preferred implementation of the highway central divider nursery stock root water feeder, the semi-encircling root water supply component includes a linear water delivery pipe, and a horizontally arranged semi-encircling water delivery pipe is connected to the linear water delivery pipe. A plurality of water supply pipes distributed in a circumferential array are butted on the semi-encircling water delivery pipe. A plurality of water supply holes are linearly arranged along the length of the water supply pipe. When the semi-encircling root water supply component and the semi-encircling root air supply component are inserted into each other, the water supply pipes and the air supply pipes are spaced and staggered with each other.

[0023] With the above solution, in order to achieve uniform water supply, water flows from the linear water delivery pipe into each semi-encircling water delivery pipe, and then enters the water supply pipe. Finally, the water flows out from the water supply holes to supply water evenly around the root system.

[0024] After adopting the above technical solution, the beneficial effects of the present invention are:

[0025] 1. First, by setting up a semi-encircling root air supply component, the outside air can directly reach the root system of the seedlings through the semi-encircling root air supply component, increasing the oxygen content around the root system and facilitating the root respiration. Then, when watering the roots for a long time, the roots are not easily rotted, which is more conducive to the healthy growth of the seedlings. Second, after the semi-encircling root water supply component of the root waterer is inserted into the semi-encircling root air supply component, the whole encircling root water supply component will be more stable, and it can restrain the root system of the seedlings, thus preventing it from extending outwards and damaging the road foundation. Finally, when the root waterer is supplying water, there will be water flow impact in the water-jet drive mechanism. Through the water-jet drive mechanism, it can act on the intermittent air acceleration flow mechanism to accelerate the air flow in the semi-encircling root air supply component, providing air with faster fluidity during water supply, further increasing the oxygen content around the root system and helping the roots to carry out respiration during water absorption.

[0026] 2. To achieve uniform air supply, air is supplied from the linear air pipe to each semi-encircling air pipe, and then enters the air supply pipe. Finally, the air is discharged from the air supply holes to supply air evenly around the root system.

[0027] 3. To store the water around the root system, by setting up a water storage sponge section, the excess water in the soil will be absorbed and stored by the water storage sponge section, thus facilitating the subsequent supply to the root system. And one-third of the diameter of the water storage sponge section is cut off along its radial direction to prevent the water storage sponge section from affecting the normal air transmission.

[0028] 4. To make the intermittent air acceleration flow mechanism work, by setting up a water-jet drive mechanism, when there is water flow impact in the water-jet drive mechanism, the drive swing arm rotates with the impeller, and the drive swing arm will act on the intermittent air acceleration flow mechanism, thus realizing the work of the intermittent air acceleration flow mechanism.

[0029] 5. To accelerate the air flow in the semi-encircling root air supply component, when there is no water flow impact in the water-jet drive mechanism, the drive swing arm remains stationary and cannot press down the auxiliary push rod. At this time, under the elastic action of spring 1, the steel wire is taut, and the control valve core will be pulled by the steel wire to open the air inlet valve port. At this time, the one-way air inlet valve assembly is in the open state, so that the air can flow naturally inside and outside the air box. When there is water flow impact in the water-jet drive mechanism, the drive swing arm rotates with the impeller. When the drive swing arm rotates, it will press down the auxiliary push rod. At this time, spring 1 is compressed and the steel wire is slack. The control valve core closes the air inlet valve port under the elastic action of spring 2. At this time, the one-way air inlet valve assembly is in the closed state, and the air will be compressed downward through the corrugated air plug, so that the air can flow quickly inside and outside the air box.

[0030] 6. To achieve uniform water supply, water flows from the linear water pipe into each semi-encircling water pipe, then enters the water supply pipe, and finally discharges from the water supply holes to supply water evenly around the roots. Description of the Drawings

Specific implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0050] AsFigures 1 to 4 As shown in the figure, a water feeder for the roots of seedlings in the central isolation belt of an expressway includes two semi-encircling root water supply components 1 installed oppositely to each other. The two semi-encircling root water supply components 1 can form a complete encircling root water supply component; a semi-encircling root air supply component 2 is also inserted and installed in each semi-encircling root water supply component 1. The semi-encircling root water supply component 1 and the semi-encircling root air supply component 2 are both buried underground; a main water supply pipe 103 is docked above each semi-encircling root water supply component 1, and the main water supply pipe 103 is installed on the ground; a water flushing transmission mechanism 4 is docked and installed between each main water supply pipe 103 and the semi-encircling root water supply component 1, and an intermittent air acceleration flow mechanism 5 is docked above each semi-encircling root air supply component 2; the water flushing transmission mechanism 4 and the intermittent air acceleration flow mechanism 5 are at the same height and act on the intermittent air acceleration flow mechanism 5. When there is water flow impact in the water flushing transmission mechanism 4, the intermittent air acceleration flow mechanism 5 can be actuated through the water flushing transmission mechanism 4 to accelerate the air fluidity in the semi-encircling root air supply component 2.

[0051] First of all, by setting the semi-encircling root air supply component 2 in this root water feeder, the outside air can directly reach the roots of the seedlings through the semi-encircling root air supply component 2, increasing the oxygen content around the roots and contributing to the root respiration. Then, when watering the roots for a long time, the roots are not easily rotten, which is more conducive to the healthy growth of the seedlings; secondly, after the semi-encircling root water supply component 1 of this root water feeder is inserted into the semi-encircling root water supply component 1, the entire encircling root water supply component will be more stable, and it can restrain the roots of the seedlings, thus preventing them from extending outward and damaging the road foundation; finally, when this root water feeder is supplying water, there will be water flow impact in the water flushing transmission mechanism 4. The intermittent air acceleration flow mechanism 5 can be actuated through the water flushing transmission mechanism 4 to accelerate the air fluidity in the semi-encircling root air supply component 2, providing air with faster fluidity during water supply and further increasing the oxygen content around the roots to help the roots breathe during water absorption.

[0052] As Figure 5 shown in the figure, the semi-encircling root air supply component 2 includes a linear air pipe 201, and a plurality of semi-encircling air pipes 202 arranged horizontally and side by side in the up and down direction are connected to the linear air pipe 201; a plurality of air supply pipes 203 distributed in a circumferential array are commonly docked on all the semi-encircling air pipes 202, and a plurality of air supply holes 204 linearly arrayed along its length are opened on the air supply pipes 203. In order to achieve uniform air supply, air is supplied from the linear air pipe 201 into each semi-encircling air pipe 202, and then enters the air supply pipe 203. Finally, the air is discharged from the air supply holes 204 to supply air evenly around the roots.

[0053] As Figures 6 to 7As shown, multiple slots 205 are provided on the pipe wall of the semi-encircling gas pipeline 202 in a circumferentially arrayed manner, and each slot 205 is filled with a water storage sponge section 206; among them, the water storage sponge section 206 is cut off one-third of its diameter along its radial direction, and a ventilation hole 207 is radially penetrated through the center of the water storage sponge section 206. In order to store the water around the roots, by setting the water storage sponge section 206, the excess water in the soil will be absorbed and stored by the water storage sponge section 206, so as to facilitate the subsequent supply to the roots; and the water storage sponge section 206 is cut off one-third of its diameter along its radial direction to avoid the water storage sponge section 206 affecting the normal transmission of air.

[0054] As Figures 8 to 9 , Figures 12 to 13 shown, the water-jet drive mechanism 4 includes a water flow box body 401, and an impeller 402 is rotatably connected inside the water flow box body 401; a guiding seat 403 is fixed inside the water flow box body 401 above the impeller 402; a transmission swing arm 404 that can rotate with the impeller 402 is fixedly installed outside the water flow box body 401, and the length of the transmission swing arm 404 is greater than the length of the fan blade; among them, the guiding seat 403 is inclined in a "slide shape", and an opening eccentric to one side of the rotation axis of the impeller 402 is provided at the bottom of the guiding seat 403, and the fan blade of the impeller 402 corresponds to the lower part of the opening. In order to realize the operation of the intermittent air acceleration flow mechanism 5, by setting the water-jet drive mechanism 4, when there is water flow impact in the water-jet drive mechanism 4, the transmission swing arm 404 rotates with the impeller 402, and the transmission swing arm 404 will act on the intermittent air acceleration flow mechanism 5, so as to realize the operation of the intermittent air acceleration flow mechanism 5.

[0055] As Figures 10 to 11 , Figures 14 to 15 shown, the intermittent air acceleration flow mechanism 5 includes an air box body 501, a push block 502 that can move up and down is installed inside the air box body 501, and a corrugated air plug 503 that is simultaneously in interference fit with the inner wall of the air box body 501 is installed in a limited way on the outside of the push block 502; a main push rod 504 is fixed above the push block 502 and is vertically arranged; a guiding seat 505 is fixed at the top of the main push rod 504, and the guiding seat 505 is slidably installed on a guiding shaft 506 fixed inside the air box body 501, and a spring 507 that pushes the guiding seat 505 to move upward is sleeved on the guiding shaft 506; a secondary push rod 508 that is horizontally arranged and penetrates to the outside of the air box body 501 is fixed on the side wall of the main push rod 504, and the secondary push rod 508 is located in an avoidance groove 509 vertically opened on the side wall of the air box body 501; the secondary push rod 508 can be in contact with the rotating transmission swing arm 404, and among them, when the secondary push rod 508 is in contact with the transmission swing arm 404, it can press down the secondary push rod 508;

[0056] Among them, two symmetrically arranged one-way intake valve assemblies 6 are installed at the lower end of the air box body 501. The bottom of the push block 502 is respectively traction-connected to the one-way intake valve assemblies 6 through two steel wires 510, and the opening and closing of the one-way intake valve assemblies 6 are controlled through the steel wires 510. Two sets of wire bundling rollers 511 are fixed on the inner side wall of the air box body 501 above the one-way intake valve assemblies 6, and the steel wires 510 are simultaneously limited between the two sets of wire bundling rollers 511.

[0057] Among them, the one-way intake valve assembly 6 includes an intake valve housing 601. An intake valve port 602 is opened at the center of the intake valve housing 601. A control valve core 603 is installed inside the intake valve housing 601 at the location of the intake valve port 602. The control valve core 603 can completely block the intake valve port 602. The control valve core 603 is slidably installed on a second guide shaft 604 fixed in the intake valve port 602. A second spring 605 that pushes the control valve core 603 to move towards the location of the intake valve port 602 is sleeved on the second guide shaft 604. The steel wire 510 is traction-connected to the control valve core 603.

[0058] In order to accelerate the air fluidity inside the semi-encircling root air supply assembly 2, when there is no water flow impact in the water flushing transmission mechanism 4, the transmission swing arm 404 remains stationary, and the transmission swing arm 404 cannot press down the auxiliary push rod 508. At this time, under the elastic action of the first spring 507, the steel wire 510 is taut, and the control valve core 603 is pulled through the steel wire 510 to open the intake valve port 602. At this time, the one-way intake valve assembly 6 is in an open state, so that air naturally circulates inside and outside the air box body 501. When there is water flow impact in the water flushing transmission mechanism 4, the transmission swing arm 404 rotates with the impeller 402. When the transmission swing arm 404 rotates, it will press down the auxiliary push rod 508. At this time, the first spring 507 is compressed, the steel wire 510 is slack, and the control valve core 603 closes the intake valve port 602 under the elastic action of the second spring 605. At this time, the one-way intake valve assembly 6 is in a closed state, and the air is compressed downward through the corrugated air plug 503, so that the air quickly circulates inside and outside the air box body 501.

[0059] As Figure 16 shown, the semi-encircling root water supply assembly 1 includes a linear water delivery pipe 101. A horizontally arranged semi-encircling water delivery pipe 102 is connected to the linear water delivery pipe 101. A plurality of water supply pipes 103 distributed in a circumferential array are butted on the semi-encircling water delivery pipe 102. A plurality of water supply holes 104 linearly arranged along its length are opened on the water supply pipes 103. When the semi-encircling root water supply assembly 1 and the semi-encircling root air supply assembly 2 are inserted into each other, the water supply pipes 103 and the air supply pipes 203 are distributed at intervals and staggered with each other. In order to achieve uniform water supply, water flows from the linear water delivery pipe 101 into each semi-encircling water delivery pipe 102, and then enters the water supply pipes 103. Finally, the water flows out from the water supply holes 104 to supply water evenly to the surrounding of the root system.

[0060] Working principle of the present invention:

[0061] This root water feeder is used for supplying water and air to the seedlings in the central isolation belt of expressways.

[0062] During application, first insert the semi-encircling root water supply component 1 and the semi-encircling root air supply component 2 into each other, and then set the two inserted semi-encircling root water supply components 1 and semi-encircling root air supply components 2 oppositely, then a complete encircling water supply and air supply device can be formed. Then bury the semi-encircling root water supply component 1 and the semi-encircling root air supply component 2 together underground at the location where the seedlings are located.

[0063] When there is no water supply, as Figures 8 to 11 shown, there is no water flow impact inside the water-jet drive mechanism 4. At this time, the drive swing arm 404 is stationary, and the drive swing arm 404 cannot press down the auxiliary push rod 508. At this time, under the elastic action of the first spring 507, the steel wire 510 is taut, and the control valve core 603 will be pulled by the steel wire 510 to open the air inlet valve port 602. At this time, the one-way air inlet valve assembly 6 is in an open state, so that air can naturally circulate inside and outside the air box 501. At this time, the root system can contact the naturally flowing air, increasing the oxygen content around the root system, and the root system is not easily rotten, which is more conducive to the healthy growth of seedlings.

[0064] When water is supplied, as Figures 12 to 15 shown, there is water flow impact inside the water-jet drive mechanism 4. At this time, the drive swing arm 404 rotates with the impeller 402. When the drive swing arm 404 rotates, it will press down the auxiliary push rod 508. At this time, the first spring 507 is compressed, the steel wire 510 is relaxed, and the control valve core 603 closes the air inlet valve port 602 under the elastic action of the second spring 605. At this time, the one-way air inlet valve assembly 6 is in a closed state, and the air will be compressed downward through the corrugated air plug 503, and so on in a cycle, so that air can circulate quickly inside and outside the air box 501.
